This package is an R wrapper around the Telegram Bot API.

It allows to send messages (text, Markdown, images, files) from R to your smartphone.

More infos on telegram's bot api can be found here and here.

How to install the package?

For the stable version:


For the development one:


First time setup

First you have to talk to the botfather to create a new bot; answer few questions regarding bot's name and you're ready to go.

After you've done, the botfather returns a token (which has to be kept secret) that lets you handle your bot; we need this token when creating the bot object on the R side. Following Hadley's API guidelines it's unsafe to type the token just in the R script. It's better to use enviroment variables set in .Renviron file.

So let's say you have named your bot RBot (it's the first question you've answered to the botfather); then put the following line with your token in your .Renviron:


If you follow the suggested R_TELEGRAM_BOT_ prefix convention you'll be able to use the bot_token function (otherwise you'll have to get these variable from Sys.getenv).

After you've finished these steps restart R in order to have working environment variables.

How to connect R with Telegram

Now you should be able to obtain a connection to your bot with these commands:


## Create the bot object
bot <- TGBot$new(token = bot_token('RBot'))

## Now check bot connection it should print some of your bot's data

## Now, on the phone, find and say something to your bot to start a chat
## (and obtain a chat id).
## ...

## Here, check what you have inserted

## You're interested in the variable: in order to set a
## default chat_id for the following commands (to ease typing)

After a bit using the package, you'll probably want to set the chat_id to your user id (or more generally, have something like an addressbook to store users' ids). If you put this in your .Renviron:


you'll be able to use the user_id function, eg like this:


Examples of methods currently implemented

Once you've followed the previous section, run the following commands and look at your phone.

## Send some messages..
bot$sendMessage('This is text')
## Markdown support for messages
md1 <- "*bold* _italic_ [r-project]( "
md2 <- " try `x <- rnorm(100)` at the console ..."
## below left spaces just for github displaying (not needed in the .R src)
md3 <- "
you can have
x <- runif(100)

too " bot$sendMessage(md1, parse_mode = 'markdown') bot$sendMessage(md2, parse_mode = 'markdown') bot$sendMessage(md3, parse_mode = 'markdown')

Send a image/photo

png('test.png') plot(rnorm(100)) bot$sendPhoto('test.png', caption = 'This is my awesome graph')

Send a document (can be any file)

help(TGBot, help_type = 'pdf') bot$sendDocument('TGBot.pdf')

Forward a message

bot$forwardMessage(from_chat_id = 123456, chat_id = 123456, message_id = 35)

Send a location

bot$sendLocation(44.699, 10.6297)

Send a sticker

bot$sendSticker(system.file('r_logo.webp', package = 'telegram'))

Send a video

library(animation) saveVideo({ set.seed(1) nmax <- 10 ani.options(interval = 0.4, nmax = nmax) x <- c() for (i in 1:nmax){ x <- c(x, rnorm(1)) plot(cumsum(x), lty = 2, xlim = c(1, nmax), ylim = c(-5, 5)) abline(h = 0, col = 'red') } }, = 'animation.mp4') bot$sendVideo('animation.mp4')

Send mp3 audio files

bot$sendAudio(system.file('audio_test.mp3', package = 'telegram'), performer = 'espeak (')

Send voice (opus encoded .ogg files)

bot$sendVoice(system.file('voice_test.ogg', package = 'telegram'))


bot$getUserProfilePhotos(user_id('me')) # <- alternatively, variable in getUpdates bot$getUserProfilePhotos(user_id('me'), destfile = 'me.png')


bot$getFile('asdasdasdqweqweqwe-UdYAAgI', # <- file_id from getUserProfilePhotos 'me_small.png')
